为了维护修理的方便,液压系统油箱出油口和泵的进油口之间通常设有截止阀,以便检修时关闭油箱,避免油箱内油液外流,造成污染和浪费.过去,该阀均采用球式截止阔——球阀,系统工作时球阀处于开启位置,检修时拧转球阀使之处于关闭位置.选用球阀,管路安装复杂,特别是在较大排量泵时,吸油管相应较粗,对应的球阀结构很大,连接更加不便。最近,我厂研制了一种新型油箱专用截止阀,克服了
In order to maintain the convenience of repair, there is usually a stop valve between the hydraulic system oil tank outlet port and the pump inlet port, so as to close the oil tank during inspection and avoid the outflow of oil in the oil tank, resulting in pollution and waste. Ball-type cut-off wide ball valve, the system is working when the ball valve is in the open position, when the repair screwed the ball valve so that it is in the closed position.Using the ball valve, the pipeline installation is complex, especially in the larger displacement pump, the suction pipe relatively thick , The corresponding ball valve structure is very large, more inconvenient to connect. Recently, our factory developed a new type of special globe valve, to overcome
